Question

Alkenes combine with carbon monoxide and hydrogen in presence of octacarbonyldicoblat as catalyst under high temperature and pressure to form

• A. Aldehydes which can be further reduced to alcohols by hydrogen
• B. Alkanes which are formed by addition of hydrogen
• C. Alcohols formed by reaction of CO and hydrogen
• D. Ketones which can be further reduced to aldehydes by hydrogen.

Answer 1

Answer: (A)

Aldehydes which can be further reduced to alcohols by hydrogen

Answer 2

: $R - CH = CH_{2} + H_{2} + CO \rightarrow \underset{aldehyde}{RCH_{2}CH_{2}CH_{2}CHO}$$$\overset{\quad H_{2}\quad}{\rightarrow}RCH_{2}CH_{2}CH_{2}OH$$
